This paper proposes spongent – a family of lightweight hash functions with hash sizes of 88 (for preimage resistance only), 128, 160, 224, and 256 bits based on a sponge construc...

In this work, we study a new multivariate quadratic (MQ) assumption that can be used to construct public-key encryption schemes. In particular, we research in the following two di...
Recently, Aumann and Lindell introduced a new realistic security model for secure computation, namely, security against covert adversaries. The main motivation was to obtain secure...
Abstract. Users are often forced to trust potentially malicious terminals when trying to interact with a remote secure system. This paper presents an approach for ensuring the inte...
We answer the open question of the possibility of building a digital signature scheme with proven security based on the one-wayness of a trapdoor permutation and with signatures as...
